Well this is almost a "what religion?" question, and we'll all disagree here based on our own experience, but for me, after a lot of miles on a lot of bikes over a lot of years, I've settled on Bridgestone BT45R's, magnificent tires with fantastic grip and wear characteristics, and not expensive like some of the European brands.
I've ridden on tires from France, Germany and Italy (and some "British" tires that are actually made in Asia) and none of them are better than the Bridgestones, but ALL of them are more expensive.
You can buy cheaper tires again, but then we fall into the "How much is your own life worth" scenario, as tires are safety items, and no less important than brakes or shockers. Cheers, Terry.
